Abstract
An upward acting sectional door is formed of rectangular door sections which are interconnected to each other by a continuous hinge comprising opposed partial arcuate hinge members formed on a lower rail of an upper section and an upper rail of an adjacent lower section and engaged with a third hinge member comprising an elongated tubular pin having a D-shaped cross section. The hinge pin is secured against rotation by retainer members at opposite ends of one of the door sections. The hinge permits lateral assembly and disassembly of one door section relative to the other. Additional load bearing hinge members are provided connected to the lateral side edges of adjacent door sections and are interconnected by support members disposed in the tubular hinge pin for transferring part or all of the forces between adjacent door sections thereby allowing the arcuate hinge members to function substantially as cooperating light and weatherseal members and to provide a substantially pinch proof door.
